WRENCH.

SPECIFICATION forming part of Letters Patent No. 660,963. dated October 30, 1900. Application filed .lune 5, 1900. Serial No. 19,152. (No model.)

To if/ZZ whom it .may concern:

Be it known that I, JOHN P. KIBLER, a citizen of the UnitedStates, residing at Eura, in the county of Page and State of Virginia, have invented anew and useful Wrench, of which the following is a specification.

This invention relates to Wrenches; and one object thereof is to provide a simple and inexpensive device of this character that may be used with equal advantage upon variousshaped nuts or pipes.

' A further object is to provide improved vmeans for quickly and easily adjusting the jaws to different-sized nuts or pipes.

The preferred form ot' in ven tion is described in the following specification and shown in the drawings which accompany and form a part thereof, and in Which- Figure 1 is a perspective view showing the jaws in open position. Fig. 2 is aside elevation of the same, showing the jaws closed. Fig. 3 is a cross-section on the line 3 3 of Fig. 2.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

In carrying out the invention as shown a stationary shank 1 is provided, one end portion of which is rounded to form a handle 2, the other end being curved and serrated to form a stationary jaw 3.

Slidably mounted upon the stationary shank 1 is the movable shank 4, having at one end an odset curved arm which forms a movable jaw 5, the inner face of said arm being serrated, as at 6, and coacting with the stationaryjaw 3. The movable shank is preferably mounted upon the stationary shank by means ot' a yoke or loop 7, Which is fastened to the stationary jaw 1 and through which the movable shank 4 slides., The end of the movable shank 4 which is opposite to the jaw 5 is cut away, as at 8, said cut-away portion beingi'perforated to form a hinge-eye 9, to which is pivotally connected the bell-crankoperating lever 10. The long arm of this lever is rounded to form a handle 1l, and the short arm is bifurcated, as at 12, to form a pair of engaging arms 13, that embrace the stationary' shank l. These engaging arms are each provided 011 the side nearest the jaws with the notches 14. Projecting from both sides of the stationary shank 1 are the fulcrum-pins 15,which are adapted to engage in the notches 14 of the arms 13. For the purpose of obtaining a greater adjustment of thejaws a plurality of these pins are provided, and it will be evident that the arms 13 may be engaged over any pair of pins desired.

In operating the Wrench the jaws are placed over the pipe or nut, and the arms 13 are engaged over one of the pairs of projecting fulorum-pins. The lever 11 is then pressed toward the handle portion 2 of the stationary shank, whereupon the jaws will firmly grip the article to be operated upon.

It will thus be seen that a verysim ple and inexpensive wrench is provided that can be easily and quickly adj usted to the article that is to be operated upon and that can be used withequal advantage upon a pipe or nut.

From the foregoing it is thought that the construction, operation, and many ad vantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it Will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described theinvention, what vI claim, and desire to secure by Letters Patent, is-

1. In a Wrench, a pair of relatively xed and movable shanks provided with coacting jaws, one of said shanks being provided with a handle, and a lever pivotally connected With the other shank and provided with a bifurcated portion having a shiftable fulcrum connection with the first-named shank upon both sides thereof.

2. In a wrench, a pair of relatively Xed and movable shanks provided With coacting jaws, one of said shanks being provided With a handle, and a bell-crank lever pivotally connected at its angle with the other shank and provided with a bifurcated arm detachably and adjustably fulcrumed to the firstnamed shank upon both sides thereof.

3. In a wrench, the combination with a shank having a stationary jaw and provided with a handle portion, of a movable jaW mounted upon the stationary shank, a series IOO a bellerank lever pivoted to the movable shank, one of the arms of said lever forming a handle, the other arm beingbifureated to embrace the stationary shank and having a detachable engagement with certain of the fulerum-pins, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

JOI-IN P. KIBLER.
